+/**
+ * Returns `true` if at least one element in the `coll` satisfies an async test.
+ * If any iteratee call returns `true`, the main `callback` is immediately
+ * called.
+ *
+ * @name some
+ * @static
+ * @memberOf module:Collections
+ * @method
+ * @alias any
+ * @category Collection
+ * @param {Array|Iterable|AsyncIterable|Object} coll - A collection to iterate over.
+ * @param {AsyncFunction} iteratee - An async truth test to apply to each item
+ * in the collections in parallel.
+ * The iteratee should complete with a boolean `result` value.
+ * Invoked with (item, callback).
+ * @param {Function} [callback] - A callback which is called as soon as any
+ * iteratee returns `true`, or after all the iteratee functions have finished.
+ * Result will be either `true` or `false` depending on the values of the async
+ * tests. Invoked with (err, result).
+ * @returns {Promise} a promise, if no callback provided
+ * @example
+ *
+ * // dir1 is a directory that contains file1.txt, file2.txt
+ * // dir2 is a directory that contains file3.txt, file4.txt
+ * // dir3 is a directory that contains file5.txt
+ * // dir4 does not exist
+ *
+ * // asynchronous function that checks if a file exists
+ * function fileExists(file, callback) {
+ *    fs.access(file, fs.constants.F_OK, (err) => {
+ *        callback(null, !err);
+ *    });
+ * }
+ *
+ * // Using callbacks
+ * async.some(['dir1/missing.txt','dir2/missing.txt','dir3/file5.txt'], fileExists,
+ *    function(err, result) {
+ *        console.log(result);
+ *        // true
+ *        // result is true since some file in the list exists
+ *    }
+ *);
+ *
+ * async.some(['dir1/missing.txt','dir2/missing.txt','dir4/missing.txt'], fileExists,
+ *    function(err, result) {

+ *    }
+ *);
+ *
+ * // Using Promises
+ * async.some(['dir1/missing.txt','dir2/missing.txt','dir3/file5.txt'], fileExists)

+ *     console.log(result);
